Merck, 315M-96, PD-1 (NAT105) Mouse Monoclonal Antibody

General description
Programmed death-1 (PD-1) is expressed on activated T-cells, B-cells, and myeloid cells. Anti-PD-1 is a marker of angioimmunoblastic lymphoma and suggests a unique cell of origin for this neoplasm. Unlike CD10 and BCL6, PD-1 is expressed by few B-cells, so anti-PD-1 may be a more specific and useful diagnostic marker in angioimmunoblastic lymphoma. In addition, PD-1 expression provides evidence that angioimmunoblastic lymphoma is a neoplasm derived from germinal center-associated T-cells. PD-1 expression in angioimmunoblastic lymphoma lends further support to this model of T-cell oncogenesis, in which specific subtypes of T-cells may undergo neoplastic transformation and result in specific distinct histologic, immunophenotypic, and clinical subtypes of T-cell neoplasia.
Programmed death-1 (PD-1), also known as CD279, is a type-I transmembrane protein expressed on T-cells, B-cells, and monocytes during activation. PD-1 and its ligands (PD-L1 and PD-L2) function as an immune checkpoint pathway by regulating T-cell activation and autoimmunity. PD-1 labels follicular helper T-cells and is therefore a useful marker for angioimmunoblastic T-cell lymphoma.
